I'm easy and reputed effective
.nethod Of restoring faded ink on old
manuscripts is TO moisten the paper
with water and then paint over with
a soft brush dipped in ammonium
sulphide Most inks contain iron gen
orally combined with an organic acid
which In process of time becomes de
composed, with consequent fading of
color. The ammonium sulphide com.
bines with the iron, forming the black
iron sulphide, causing thus the reap
pearance of the original characters.
A new kind of glass has been recent
ly perfected by Prof. Abbey and DIR.
Scott under the auspices of the Prussian
Government. Common glass usually
contains about six different sub
stances, but this new glass contains
fourteen, among them the very I'M
usual constituents boron and phos-
2horus, never found in the ordinary
product. The new glass Is said to pos
sess extraordinary reflective power,
and will be used for lenses for micro
scopes and other optical apparatus, with
The expectation that present available
magnifying powers may be enlarged
1undredfold.
IMPURE ICE AS A CAUSE or DISEASE.
The State Board Of Health. having
oeen asked by the Board Of Health OF
syracuse To examine into the purity of
.ce taken from Onondaga Lake, from
he Erie Canal. at Syracuse, and from
.azenovia Lake, has not only made
careful investigation into the quality
Of ice from those sources, but has also
prepared a report on the general ques-
ton of the pathogenetic powers OF
contaminated ice. The Board comes
10 these conclusions: Ice formed in
impure water has caused sickness; IL
may contain from eight 10 ten per
cent. Of the organic matter dissolved
In the water, and in addition a very
large amount Of the organic matter
that had been merely suspended or
floating in il; II may contain living
animals and plants, ranging in size
from visible worms down 10 the
minutest spores, and the vitality of
these organisms may be unaffected by
freezing.
PREVENTIVE MEDICINE.
DIR. G. r. Illinsworth thus writes in
the Ned. Press
One of our great aims as physicians
is TO prevent disease; another is 10 cut
short its course when developed. Our
power in these directions finds fun
scope among that class of disorders
now generally recognized as depending
upon the reception, growth, and de-
velopment in the tissues Of micro-or-
ganic life in one shape or another.
BY the continual suppression of the
growth and development of these forms
of cell life, we may, indeed, hope at
length to erase the names OF the dis
eases they cause from the category OF
those ..ills that flesh is heir to-" The
diseases / refer TO are scarlet fever,
diphtheria, measles, whooping cough,
rheumatic fever, chicken-pox, small
pox, syphilis, hydrophobia, yellow
fever, Ct hoe genus OhJle.
The germicide remedy have found
TO answer as specific and prophylac-
tic In such diseases is the biniodide of
hercury given in solution OF potassic
fodide.
THE FOOD OF MAN.
There is no doubt that man can ex-
ist on vegetable diet. He can OBJ
tain from the plant world, digest and
assimilate, those materials which are
needful for the repair of his own
tissues. The arts concerned in the
preparation of food will also undoubt-
eddy aid him in his conversion of veg
etable into animal equivalents, and
will supplement his powers by short
ening considerably the period required
for gastric digestion. stu. after all
has been said, IL must be allowed that
the labor OF the allmentary tract is
better adjusted and the formation OF
sound tissues more assured by the use
of a mixed diet II, on the one hand,
we assert the prcvsd value of hydro
carbons 10 organic combustion not
merely as heat producers, but as
sources OF energy in support of our
use Of vegetables. we must also main
